Be it known that I, S'rANIsLAw DOMAN- SKI, a citizen of Poland, residing, at Elyria, in the county of Lorain and Stateof Ohio, have invented certain new and useful Iniprovements in Plows, of which the following is a specification.

. The primary object of the present invention resides in the provision of a plow having mold boards at opposite sides of the plow point hinged to swing in directions so that the spreading of earth may be readily controlled by adjustingthe position of the mold boards with respect to the longitudinal axis of the plow point.

With the above and other objects in vlew, this invention consists in the novel form, combination and arrangement of parts herein fully described and shown in the accompanying drawings, wherein like reference characters indicate similar parts throughout the several views;

In the drawings,

Figure 1 is a side elevational view of a plow constructed in accordance with the present invention, one of the mold boards being broken away,

Fig. 2 is a top plan view of the same,

Fig. 3 is a rear elevation showing the links connecting the hinged mold board to a board of the plow frame, and

Fig. 4 is a cross sectional view taken on line IV-IV of Fig. 1.

Referring more in detail tothe accompanying drawings, there is illustrated a plow beam 5 having an upwardly arched rear portion to the rear end of which 1s connected a pair of handle arms 6 converging outwardly and upwardly and carrying hand grips 7 upon the terminal ends thereof. A cross brace 8 extends between the outer ends of the handle arms 6 for purposes of strengthening the same and holding the hand grips in affixed relative position, and are further braced by the rods 9 extending between the cross brace 8 and the upper face of the plow beam 5, the forward ends being connected to the beam 5 by the bolt 10 The forward end of the beam 5 carries an ordinary form of clevis 11 secured by straps 12 to the beam and which straps carry a reotan gnlar frame 13 inclosing the beam 5 and through which the upper forked end 14.- of a wheel carrying bracket is adapted to slidably extend, the bracket carrying a ground engaging wheel 15 at its lower end. A screw Patented a my 5, ieai.

16 extends through alined openings in the opposite sides of the frame 13 and is adjustably received in the openings 17 formed in the forks 14. i

The plow structure includes a runner 18 having a plow point 19 at its forward. end, the runner 18 being carriedbythe upwardly and rearwardly inclined shaft 20 secured at its upper end to thebeam 5 by the bolt 10. The shaft 20 is held immovable relative to the beam 5 by braces extending between the beam and the shaft, Fig. 1 showing the lower ends of the arms 6 straddling the beam 5 and secured thereto as at 21 and being extended as at 22 for a bolt connection 23 with the shaft 20, the bolts 23 serving as a connecting means for the forward rods 24 extending between the shaft 20 and the beam 5 and being connected at their forward ends to the beam as at 25. A. brace extends between the extreme rear end of the beam 5 and the runner 18 and includes a pair of bars 26 and 27 connected at their upper ends as at '28 to the beam 5 while the lower ends are connected as at 29 to the runner 18 in spaced relations. 1

As shown in Fig. 4,. the shaft 20 is triangular in crosssection and is adapted to have secured thereabout the mold boards of the plow, the mold boards including a for ward. V-shapcd frame 30 inclosing the shaft 20 and secured thereto by pins 31 extending I transversely therethrough, the rear edges of the frame 30 extending slightly beyond the rear edge of the shaft 30 and having hingedly connected at eachside of said shaft to the projecting ends as at 30, mold boards 32. In order to provide an adjustment for the angular position of the mold boards relativeto the longitudinal axis of the runner 18 there is provided aneye 33 carried by the rear face of each mold board 32 and having secured thereto links 34 provided with openings 35 adapted to register when overlapped as shown in Fig. 3 for the reception of a retaining screw 36 carried by the rear brace arm 26.

From the above detailed description of the invention, it is thoughtthat the construction and operation thereof will be readily apparent, it being noted that the mold boards are freely movable upon their hinge connections 30' with the forward frame 30 of the plow and are rigidl retained in adjusted positions by the links 34 connecting the same to the brace arm 29 between the plow beam 5 and the runner 18.

With an adjustable plow board of this character, plowing operations of many difi erent kinds may be performed and movement of the earth excavated by the point 19 and the frame 13 easily controlled;

lVhile thereis herein shown and described what'is believed to be the preferable embodiment of the invention, it is nevertheless to be understood that minor changes may be made in thenovel form, combination and arrangement oi 7 parts without departing from the spirit and scope of the invention as claimed. 7

Whatis claimed as new is z A plow of the class described comprising a beam, a ground engaging wheel adjustablycarried by the forward end thereof, handles carried by the rear end of said beam,

a runner, a shaft extending between the beam and the runner, braces extending forwardly and rearwardly of said shaft and connected to said shaft and beam, a pair oi? brace arms havingtheir upper ends ad-
